Introduction
The Yorkville Sound YX18SP offers the best value in an 18-inch active subwoofer enclosure. Created as
an easy-to-setup addition to any P.A., the YX18SP will extend the bass of a typical sound system with
the least amount of complication.
Configuration
The Yorkville Sound YX18SP may be used in several different configurations. The basic system is
a single YX18SP used with a pair of full range loudspeakers, typically the Yorkville Sound YX15P.
Multiple YX18SPs can also be used along with multiple full range enclosures if more bass output
is required. The YX18SP accepts and combines signals from stereo line level sources as well as
handling mono sources. Multiple YX18SPs can be daisy chained through the Link jacks while full
range loudspeakers can be properly fed a filtered signal from the High Pass Output jacks.
1. YX18SP Level Control
The YX18SP Level control sets the amount of bass added to the sound system by the YX18SP. This
adjusts for the relative sensitivity of the companion full-range speakers and the desired system
frequency response. This control should be set by listening while operating at a medium level (i.e.
before the onset of limiting) and then not changed. It is not possible to set this control properly at
high levels since the limiter will be determining the output level.
A setting of 0 dB on the YX18SP Level control is the correct starting point when setting up a sound
system. From there, adjustments can be made for the best sound. The 0 dB mark refers to the setting
that will give full power when the line input is used and the input signal is at a level of +4 dBV.

2. Input Jacks

Use the input jacks to feed the YX18SP with a mono or stereo from your source. It is preferred that
your source go directly to the YX18SP and then be looped up to your full range loudspeakers via
the High Pass Output jacks.
For mono signals, the Left/Mono jack will accept a ¼-inch or XLR cable. When using stereo
signals, the YX18SP will sum the Left and Right signals internally.
Note: stereo separation is maintained for signals leaving the Link and High Pass Output jacks.
3. Link Jacks
The Link jacks are directly connected to the input jacks. Use these jacks to send your source
signal on to additional YX18SP subs.
